Abstract

LA INVENCION SE REFIERE A UN GENERADOR DE PRESION HIDRAULICA QUE INCLUYE, EN UN CUERPO (1), UN CONJUNTO DE PISTONES (2) QUE DELIMITA UNA CAMARA DE PRESION (12) Y QUE COMPRENDE UN CILINDRO (21) EN DONDE UN ORIFICIO (211) RECIBE UN PISTON AUXILIAR (22) QUE DELIMITA UNA CAMARA DE COMPENSACION DE VOLUMEN VARIABLE (23) QUE CONTIENE UN ELEMENTO DEFORMABLE (5) QUE SIRVE PARA EJERCER UNA FUERZA ELASTICA ENTRE EL PISTON AUXILIAR (22) Y LA EXTREMIDAD OBTURADA (210) DEL CILINDRO (21). DE ACUERDO CON LA INVENCION, LA CAMARA DE COMPENSACION (23) SE COMUNICA CON LA CAMARA DE PRESION (12) A TRAVES DE UNA RESTRICCION (221) SITUADA EN UN ORIFICIO LONGITUDINAL (222) DEL PISTON AUXILIAR (22), ESTANDO SUJETADA LA JUNTA DE ESTANQUEIDAD (4) QUE CIERRA LA CAMARA DE PRESION (12) POR UNA PARTE (220) DEL PISTON AUXILIAR QUE PERMANECE FUERA DEL SEGUNDO ORIFICIO (211). EL GENERADOR DE LA INVENCION SE APLICA PARA AMORTIGUAR VARIACIONES DE PRESION.THE INVENTION REFERS TO A HYDRAULIC PRESSURE GENERATOR THAT INCLUDES, IN A BODY (1), A SET OF PISTONS (2) THAT DELIMINATES A PRESSURE CHAMBER (12) AND THAT INCLUDES A CYLINDER (21) WHERE A HOLE (211 ) RECEIVES AN AUXILIARY PISTON (22) THAT LIMITS A VARIABLE VOLUME COMPENSATION CHAMBER (23) THAT CONTAINS A DEFORMABLE ELEMENT (5) THAT SERVES TO EXERCISE AN ELASTIC FORCE BETWEEN THE AUXILIARY PISTON (22) OF THE CYLINDER (21). IN ACCORDANCE WITH THE INVENTION, THE COMPENSATION CHAMBER (23) IS COMMUNICATED WITH THE PRESSURE CHAMBER (12) THROUGH A RESTRICTION (221) LOCATED IN A LONGITUDINAL HOLE (222) OF THE AUXILIARY PISTON (22), WHICH IS HOLDING THE JOINT SEALING (4) THAT CLOSES THE PRESSURE CHAMBER (12) BY A PART (220) OF THE AUXILIARY PISTON THAT REMAINS OUTSIDE THE SECOND HOLE (211). THE GENERATOR OF THE INVENTION IS APPLIED TO DAMPER PRESSURE VARIATIONS.
